Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed July 7, 1910. Serial No. 570,765.

To all whom it may con cam:

Be it known that I, lVILHnLM WEFER, a subject of the Emperor of Germany,and a resident of Ufer, near Vogelsang, Westphalia, Germany, haveinvented a certain new and useful Street-Sweeper, of which the followingis a specification.

The present invention relates to a machine of the kind used for takingup the refuse previously swept up into rows in a street, such refusebeing passed by a roller brush onto an elevator and delivered by meansof the latter into a receptacle.

According to the present invention the elevator and the collectingbrush, which elements are narrower than the machine frame, are adaptedto be disposed at one side in said frame so that refuse placed near thecurb stone can be more conveniently taken up. Elevator and brush are,moreover, adapted to be adjusted from one side to the other of themachine so that refuse may be taken up at either side of the streetwithout reversing the traveling direction of the machine.

The invention is illustrated by way of eX- ample in the accompanyingdrawings, Figure 1 representing a side view of the machine, partly insection, Fig. 2, a plan of the same, and Fig. 3, a view of the lowerpart of the brush and elevator on an enlarged scale. Fig. 4 is a sideView of the machine on an enlarged scale, partly in section.

On the axles a and Z) of the road-wheels c and (Z a machine frame 6 ismounted. Be tween the brackets g on said frame a rotatable shaft f-and afixed shaft 70 are arranged, the former being rotated through the mediumof the road-wheels o. A roller brush it is slidably feathered on theshaft f and is controlled by an arm 7 the forked end of which is fittedwith lugs 8 engaging a circular groove in the boss 9 of the brush. Thearm 7 is firmly connected to one end of a sleeve 5 which is loose on theshaft 70 and which is adapted to receive a rotatable supporting roller2' for the elevator m. A collar 6 on the other end of the sleeve holdsthe roller on the latter, and roller and brush are compelled by the arm7 to keep in a registering position. The elevator apron m is guided onthe roller Z which is slidably feathered on a shaft 17., the latterbeing rotatably mounted between brackets on upright pillars 0 androtated by means of a chain or the like from the axle a. Underneath thebrush it a guide-plate g is provided along which the refuse is passed bythe brush and delivered to the elevator apron m. This plate is hinged toa plate T which is concentric with the shaft 70 and held, by bracketsconnected to the sleeve 5, close to the elevator apron to prevent therefuse from falling through. An out-ward bend at the lower end of theplate 1 prevents an engagement of the same with the elevator apron. Theplate 9 is actuated by a spring .9 so as to be resiliently held with itslower end against the ground. A rounded bead or rib t is provided on itsabutting edge to guide the plate over projections on the ground. Theelevator is covered by a plate or board a which is extended along theframe 6 and turned down over the brush it to prevent the refuse beingscattered by the latter. As the machine is driven along the road, thebrush it, which is rotated at high speed, passes the refuse along theplate g to the elevator apron m which, being fitted with cross-ribs p inknown manner, conveys the same over the roller Z and delivers it bymeans of a chute 13 into a wheeled receptacle. The latter may either becoupled to the machine or driven separately, as long as it can easily beexchanged for a fresh one when full.

F or the purpose of adjusting elevator and brush laterally in themachine frame so that, While the machine is being driven in the samedirection, refuse can be taken up at either side of the road, thefollowing arrangement is provided :A screw-spindle 1 is rotatablymounted across the machine in bearings 3 connected to oblique stays 3and fitted at both ends with hand wheels l. The rotation of the spindleadjusts the position of a nut -2 fitted on its screw thread. A bracket 2on one of the stays 3 has a doublearmed lever w pivoted thereto. One endof said lever is hinged to the nut 2, and the other end, which isbifurcated, engages a circular groove w in a boss 4; on the roller Z,the position of the latter being thus controlled by the nut 2. In thesame manner a double-armed lever 12, pivoted to a bracket 11, has onearm hinged to the nut 2 and the other to a bracket 10 on the arm 7 whichis therefore, together with the brush it and the roller 2', alsocontrolled by the nut 2. The elements being, as previously noticed,slidable on their shafts, an adjustment thereof from one side of themachine to the other can thus be effected by rotating the spindle 1.

I claim:

1. A refuse-collecting machine, comprising a .Wheeled frame, a shortbrush roller mounted in the frame and rotated by the road-Wheels fortaking up the sweepings, a resilient scoop along which the sweepings areguided, an elevator registering With the brush roller and With the scoopto receive the sWeepings from the latter, a chute for discharging thesweepings, and means for adjusting brush, scoop and elevator from oneside of the machine frame to the other, substantially as set forth.

2. A refuse-collecting machine, comprising a Wheeled frame, a shortbrush roller slidably feathered on a rotatable shaft, an elevatorregistering With the roller and also slidably arranged on its shafts, aresilient scoop to guide the svveepings from the brush roller to theelevator, means for rotating roller and elevator, and means foradjusting them together With the scoop from one side of the machineframe to the other, substantially as set forth.

3. A refuse-collecting machine, comprising a Wheeled frame, a shortbrush roller slidably feathered on a rotatable shaft, a sleeve guided ona stationary shaft behind the roller, bifurcated arms at the ends ofsaid sleeve engaging grooves in the bosses of the roller, an elevatorhaving one guide roller rotatably mounted on said sleeve, a resilientscoop for guiding the sweepings from the brush roller to the elevator,means for rotating brush roller and elevator, and means for adjustingthem together with the scoop from one side of the machine frame to theother, substantially as set forth.

4. A refuse-collecting machine, comprising a Wheeled frame, a shortbrush-roller slidably feathered on a shaft rotated by the road-Wheels,an elevator registering with the roller and slidably arranged on itsshaft, a resilient. scoop for guiding the sweepings from the brushroller to the elevator, arms connecting the brush roller With the lowerguide roller of the elevator andholding elevator and brush in coincidingposition, a screw-spindle rotatably mounted across the machine, a nutfitted on the screw-thread so 'as to be adjusted when the spindle isrotated, and double-armed levers hinged With one end to the nut and withthe other end to elevator and brush so that the position of theseelements can be adjusted by the rotating of the spindle, substantiallyas set forth.

5. A refuse-collecting machine, comprising a Wheeled frame, a shortbrush roller slidably feathered on a shaft rotated by the road Wheels, asleeve guided on a stationary shaft behind the roller, bifurcatedarms'at the ends of said sleeve engaging grooves in the bosses of theroller, an elevator havin one guide-roller rotatably mounted on sai.sleeve, a plate held by brackets on said sleeve close to the elevatorapron, a resilient scoop hingedly connected to said plate so as to guidethe sweepings from the brush roller to the elevator, means for rotatingthe elevator and means for adjusting the same together with the scoopand the brush roller from one side to the other of the machine frame,substantially as set forth.

In testimony whereof I have hereunto signed my name this 17th day ofJanuary 1910, in the presence of two subscribing Witnesses.
